Dave:
Not sure whether or not all Dometic fridges have this Climate Control Switch. Ours is 2008 model so perhaps the newer ones (or some models) do not have one or this feature. If it isn't mentioned in your Manual, then it appears as though you may not have such a switch.

I just checked on the Dometic website and the following models have the Climate Control feature :
DM2652, DM2662-63, DM2852, DM2862, DM3862, NDM1062, NDR1292.

In the user manual for these models, it states that "when turned on, the Climate Control will draw 12VDC continuously. Turn off when a charging source is not available".

Hope this helps.
